Not a silly question at all, but, as per hypothesis as was laid out by Bond and others in the literature, I like how Chris Turney depicts it in his book, Ice, Mud and Blood. (Link to book here). So in this framework: DO events are the abrupt warming events that start a Bond cycle with an interstadial, followed by a series of stadials and interstadials that are not as severe as the DO event itself, and then, wham: a Heinrich event, thereby culminating the Bond cycle.

I (a non-white male) was pleasantly surprised with the answers on this thread that I found on my front page, and was wondering why Reddit was so sensible... until I saw that this was /r/askwomen - no wonder!
